Massing at Osgiliath (Secrecy, 2H)

Blade of Gondolin and Sword that was Broken were both key, as was an early Gandalf for the Sp/Lo deck.

Out of secrecy after round 1, but got a Resourceful on Theodred which helped (round 2 Steward of Gondor on Frodo Baggins too).

One shot the Witch King with Aragorn, Legolas with a Rivendell Blade and Beorn, fetched off a Stand and Fight, using his +5 ability.
